[Autologous nanofat transplantation for scar treatment]

Damaging the normal skin barrier results in a cascade of reactions resulting in scar formation. Transforming growth factors cause the proliferation of fibroblasts to myofibroblasts, which keep secreting collagen. There are indications, that the proliferation might be inhibited by adipose-derived stem cells (ADSC). Nanofat is a liquid substance containing ADSC. This review is based on five observational human studies, where nanofat was injected into a variant of scars. A significant improvement was demonstrated in all the studies. Scars treated within five years has a better chance of regeneration. Randomized controlled trials are warranted.
